• Complete Part Number Configuration:
  • 330909: 3300 NSv Probe, 3/8-24 UNF thread, with stainless steel armor
  • -00: Unthreaded Length = 0 inch
  • -20: Overall Case Length = 2.0 inch
  • -05: Total Cable Length = 0.5 meter (20 inches)
  • -02: Connector Type = Miniature coaxial ClickLoc, standard cable
  • -05: Agency Approvals = Multiple Certifications
• Linear Measurement Range: 1.5 mm (60 mils), from 0.25 mm to 1.75 mm from target.
• Recommended Gap Setting: 1.0 mm (40 mils) for optimal performance.
• Sensitivity (ISF): 7.87 V/mm (200 mV/mil) with +12.5%/-20% interchangeability tolerance.
• Linearity Error (DSL): Less than ±0.06 mm (±2.3 mils) across the full range.

Technical Performance & System Compatibility

• Frequency Response: 0 to 10 kHz, suitable for capturing high-speed vibration data.
• Probe DC Resistance: 4.0 Ohms ± 0.5 Ohms (for the integrated 0.5-meter armored cable).
• Full Compatibility: This armored probe works seamlessly with existing 3300 XL 8 mm Proximity Probes systems and 3300 RAM extension cables.
• Electrical System Parameters:
  • Extension Cable Resistance: Center Conductor: 0.220 Ω/m, Shield: 0.066 Ω/m.
  • Extension Cable Capacitance: Typically 69.9 pF per meter.
  • Field Wiring: Use three-conductor shielded triad cable up to 305 meters maximum.
• Target Requirements: Minimum flat target diameter of 8.9 mm; 13 mm or larger recommended.

Robust Construction & Environmental Ratings

• Key Feature: Stainless Steel Armor protects the cable from physical damage and abrasion.
• Probe Tip: Made from chemical-resistant Polyphenylene Sulfide (PPS).
• Probe Body: AISI 304 Stainless Steel construction for corrosion resistance.
• Operating Temperature: Wide range from -52°C to +177°C (-62°F to +351°F).
• Pressure Seal: Viton O-ring seals the probe tip against differential pressure.
• Certifications: Multiple agency approvals ("-05" suffix) for use in hazardous locations.

Installation & Mechanical Guidelines

• Set the probe-to-target gap to the recommended 1.0 mm (40 mils) during installation.
• Probe Body Torque: Finger-tighten only; maximum torque is 0.56 N•m (5 in-lb).
• Connector Torque: Apply 11.3 N•m (100 in-lb) when connecting to extension cables.
• Thread Engagement: Maximum engagement length for 3/8-24 thread is 0.563 inches.
• Cable Handling: Maintain the 25.4 mm (1.0 in) minimum bend radius, even with armor.
• For small shafts (<13 mm), reduce the gap setting to minimize scale factor changes.

Packaging & Logistics

• Condition: 100% new, original, and delivered in factory-sealed Bently Nevada packaging.
• Contents: One Bently Nevada 330909-00-20-05-02-05 armored proximity probe.
• Shipping: We ship worldwide via reliable carriers: FedEx, UPS, and DHL.

Frequently Asked Questions (FAQ)

• What is the main benefit of the armored version? The stainless steel armor provides excellent protection for the cable in harsh, high-vibration, or high-risk environments.
• Is this armored 3300 NSv probe compatible with my system? Yes, it is fully interchangeable with non-armored 3300 NSv and older 3300 RAM probes and cables.
• What is the maximum field wiring distance? You can reliably use up to 305 meters (1000 feet) of cable between the probe and monitor.
• Can I use this for measuring axial position on a small shaft? Yes, but for shafts under 13 mm in diameter, you should reduce the installation gap to maintain accuracy.
